NOVA"Meteor Strike"
A 7,000-ton asteroid crashes into the earth's atmosphere, explodes and falls to earth across a wide swath near the Ural Mountains on February 15. Dubbed the Siberian Meteor, it explodes with the power of 30 Hiroshima bombs, damaging buildings and sending more than 1,000 people to the hospital. Countless digital dashboard cameras record the event creating crowd-sourced data that allows NOVA crews and impact scientists to hit the ground in Russia in search of debris from the explosion, and clues to the meteor's origin and makeup. The program also explores some even greater explosions of the past, asking if Earth is in the cross-hairs of a celestrial shooting gallery.G
